摘要： The invention relates to a method for synchronizing the frequency of a client clock with a server clock frequency, such synchronization being performed through timing packets (30) transmitted by the server towards the client through a telecommunication network, characterized in that it comprises the transmission by the server of groups (34) of timing packets (30) whereby an emission timing packet period (τ 1 ), measured between successive timing packets (30) of a same group (34), is smaller than an emission group period (τ 3 ), measured between first timing packets (30) of successive groups (34),
- Emission timing packet period (τ 1 ) being such that transmission delays of timing packets (30) within a same group (34) are practically correlated, and
- Emission group period (τ 3 ) being such that transmission delays of timing packets (30) from different groups (34) are practically uncorrelated.

摘要： A method for establishing a connection across resource domains comprises: determining source and destination end-points for the connection,
determining, by a service agent, a chain of adjacent service elements suitable for joining the source and destination end-points based on the identified edges,
requesting, by the service agent, a first service provider (35) associated to a service element in the chain to select a first connection segment embodying the service element, receiving, by the service agent, an inter-carrier communication resource identifier from the first service provider, said inter-carrier communication resource identifier indicating communication resources at an inter-carrier interface between an end point of the first connection segment and a resource domain associated to an adjacent service element in the chain,
transferring, by the service agent, the inter-carrier communication resource identifier to a second service provider (25) associated to the adjacent service element.

摘要： A method is intended for distributing a frequency reference to network clocks (NC 1 -NC 5 ), comprising a synchronization card (SC) and an interface card (IC), and belonging to a mobile network (MN) having a physical-layer-based protocol for distributing the frequency reference to the network clocks according to a chosen topology, and a packet-based protocol for distributing this frequency reference to the network clocks respecting this chosen topology. This method comprises a step (i) during which one detects a synchronization failure in a synchronization card (SC) of a failed network clock (NC 2 ) connected to neighbour network clocks (NC 1 ,NC 3 -NC 5 ), a step (ii) during which one activates a mechanism of the packet-based protocol between a master neighbour network clock (NC 1 ) and slave neighbour network clocks (NC 3 -NC 5 ), and a step (iii) during which one uses the activated protocol to transmit the frequency reference recovered by the master (NC 1 ) to the slaves (NC 3 -NC 5 ) by following the topology.

摘要： A selection method is implemented in a mobile network (BN) comprising a group (G1) of first network clocks (N111-N114) each having a local clock (LC), belonging to a link-by-link synchronization domain in which they communicate in a link-by-link synchronization scheme and communicating in an end-to-end synchronization scheme with a master clock (MC) providing a frequency reference for synchronizing the local clocks (LC). This method comprises a step (i) consisting in collecting datasets of the local clocks (LC) of this group (G1), a step (ii) consisting in comparing these collected clock datasets to determine the best one according to criteria, then in selecting the first network clock (N113) offering this best clock dataset, and a step (iii) during which the selected first network clock is configured as a frequency synchronization gateway for interconnecting the master clock (MC) in an end-to-end synchronization domain by using a domain identifier of an end-to-end synchronization domain.
